| description | Triggering a fire-and-forget invocation on a Scala Golem agent. Use when asked to trigger, enqueue, or fire-and-forget an agent method invocation using golem agent invoke --trigger. |
Triggering a Fire-and-Forget Agent Invocation
Both golem and golem-cli can be used — all commands below work with either binary.
Usage
golem agent invoke --trigger <AGENT_ID> <FUNCTION_NAME> [ARGUMENTS...]
The --trigger (or -t) flag sends the invocation request to the agent and returns immediately without waiting for the result. The invocation is enqueued and executed asynchronously by the Golem runtime.
When to Use Trigger
- When the caller does not need the return value
- When you want to start a long-running operation without blocking
- When enqueuing work for background processing
- When combined with
--schedule-at for future execution
Examples
Trigger a method with no wait
golem agent invoke --trigger 'MyAgent()' startBackgroundJob '"job-123"'
Trigger in a specific environment
golem agent invoke --trigger 'staging/MyAgent("user-123")' sendNotification '"Your order is ready"'
Trigger with an explicit idempotency key
golem agent invoke --trigger -i 'job-run-2024-01-15' 'BatchProcessor()' runDailyReport
Available Options
| Option | Description |
|---|
-t, --trigger | Required. Trigger the invocation without waiting |
-i, --idempotency-key <KEY> | Set a specific idempotency key; use "-" for auto-generated |
--no-stream | Disable live streaming of agent stdout/stderr/log |
--schedule-at <DATETIME> | Schedule the invocation at a specific time (ISO 8601 format, e.g. 2026-03-15T10:30:00Z) |
Difference from Regular Invoke
| golem agent invoke | golem agent invoke --trigger |
|---|
| Waits for result | Yes | No |
| Returns value | Yes | Only the idempotency key |
| Streams output | Yes (by default) | No |
| Use case | Synchronous calls | Fire-and-forget / background work |
Idempotency
Triggered invocations also use idempotency keys. If the same idempotency key is used, the invocation will not be executed again.
Auto-Deploy
If the agent's component has not been deployed yet and the CLI is run from an application directory, the command will automatically build and deploy the component before triggering.
Value Syntax
The agent ID parameters and method arguments use Scala syntax:
- Field names use
camelCase with = separator
- Options:
Some(value) / None
- Records:
MyRecord(fieldOne = 1, fieldTwo = "hello")
- Variants:
MyEnum.VariantName(value)
- Tuples:
(1, "hello")
golem agent invoke --trigger 'MyAgent("user-123")' sendEmail 'EmailRequest(to = "alice@example.com", subject = "Hello", body = "World")'
